I've tried both eating a little often and a lot very little and from the experiences of me and everyone I have ever spoken to in the flesh about this, it really is as simple as "more energy when you eat more".

Fasting won't give you mountains of physical pep. Sure, there is that golden time after you have done it for a while where you get great mental clarity and you feel good but you will not be voluntarily running laps or pushing your absolute peak weight in the gym.

That barrier is something you'll always feel, even if you're not pushing the limits. The fact of the matter is that barrier is closer when you are fasting.
